Conditions Report - Statewide

Rivers and Creeks

The recent rains have increased flows on the streams throughout the state. This extra moisture will surely get the substrate stirred up which can flush some of the larger insects and worms into the flow and the trout will surely be feeding heavily. This means anglers must use a bit larger and flashier presentations when fishing these conditions. The spawn beds from the Rainbows may still be active, so be cautious of redds when wading along the rivers. There are still waters that are iced over at higher elevations and shaded portions of canyons, so anglers can look to tailwaters--the waters below dams or other structures that regulates water flow. The regulated water flow keeps the spots from freezing over and provides warmth for the cold-blooded trout. Even with the warmer conditions of these waters, the fish will still behave sluggishly. Fish diets in the early spring are made up primarily of midges and an assortment of small blue-winged olive nymphs and are occasionally supplemented by larger mayflies, annelids, trout eggs, stoneflies, and even caddis larva. Spring fishing typically consists of a lot of nymph fishing since the trout are not overly active due to the cold water temperatures, so try using stonefly nymphs and imitation midges. Remember that the hatches are becoming more frequent in the spring, so keep an eye for surface activity and do not hesitate to switch to a dry fly presentation, especially during the warmest parts of the day. It is also important to be mindful of your split shot usage. With the fish being sluggish, they aren't going to divert too much energy for food, so making sure those flies drift directly in their path is important. Be sure not to use too much split shot though because the last thing you'll want to do is to have to retrieve a snag in those cold waters.

Boyd Lake

Boyd Lake is open to boating, Aquatic Nuisance Species Inspection hours for the month of May are 6:00 am-10:00 pm daily. As of 5/10/2018 water temperatures are in the low 60's fishing has been good for trout using traditional baits all over the lake. White Bass fishing has started to pick up with a few quality fish being caught. Anglers are starting to report success with crappie fishing as well. Bass fishing is getting better, jerkbaits for Smallmouth and lipless crankbaits or spinnerbaits for Largemouth. The walleye fishing has been fair with some reports of walleye being caught on blade baits, anglers should expect to work for them but the fishing is expected to get better in the coming weeks. Reminder - No fishing from marina slips or docks (next to is okay but can't use them in any way. PLEASE NOTE: Any live fish collected for use as bait may only be used in the same body of water from which they were collected. All live bait/fish from a commercial source and transported by anglers must at all times be accompanied by a receipt for the source. See the Colorado Fishing Regulations for further clarification and information.
Boyd Lake

Clear Creek

As of 5/11/2018 due to recent rain flows have increased to 324 CFS at Golden with visibility beginning to be affected by increasing flows. Fishing has been fair for browns, rainbows, and cutthroats using Stimulators, Griffith's Gnat, Midges, Pheasant Tails, and Prince Nymphs in black or dark colors. As we approach summer dry flies have begun to produce fish, Blue Wing Olive patterns have been the most productive.
Clear Creek

North Sterling

As of 5/10/2018, fishing is fair for all species. As the spring progresses to summer anglers are reporting more success with the crappie as well as walleye. Carp are also very active as the spawn begins to progress. The Reservoir is OPEN to BOATING. The Inlet is ON and the Outlet is OFF. 
North Sterling

Horsetooth Reservoir

As of 5/4/2018 the Inlet Bay and South Bay ramps are open to boating 6:00 am- 10:00 pm seven days a week. With water temperatures nearing 50 degrees fishing for walleyes and smallmouth bass has been getting better, expect to find the smallmouth along rock faces with jerk baits being a good bait. Anglers have reported catching both walleye and smallmouth using the same presentations.
Horsetooth Reservoir

Spinney Mountain Reservoir

As of 5/10/2018, water temperatures are slowly rising and the fishing is continuing to pick up. Reports from anglers are that the pike are becoming very active with many nice fish being caught. Fishing from shore has also been good for fly fishers targeting the large trout this reservoir is known for.
Spinney Mountain State Park

Saint Vrain State Park

There are 11 fishable ponds at St. Vrain that are stocked on a regular basis. Bald Eagle Pond is artificial flies and lures only. Bald Eagle Pond and Blue Heron Reservoir are trophy bass fisheries: all bass caught on these 2 ponds must be immediately returned to the water! Only 1 catfish in your standard bag and possession limit can exceed 20 inches on Blue Heron Reservoir. Blue Heron has been producing some good sized Black Crappie, Largemouth Bass, and Saugeye on jigs and lures. Trout fishing is very productive in spring and fall depending on stocking. Stocked trout are only 8-10 inches in length and we do not recommend keeping them until they have matured and are of a healthy size: around 12-24 inches. Overfishing these waters results in smaller, less productive populations.
St. Vrain

Barr Lake State park

As of 5/6/2018 warm days and lots of sun have caused the water temps to rise significantly over the past few days. Carp have started to become more active near shore, particularly in the evening hours. The lake also has been freshly stocked with trout, with small spinners and worms working this past weekend.

Arkansas River

May 9th - Upper River: The river up in Hayden Meadows is low, clear, and fairly cold. A release of 250 cfs from Twin Lakes is about doubling the flows from Lake Creek downstream. This additional water also helps to moderate the daily water temperature swings. After yesterday's increase in the Twin Lakes release, the water below the Lake Creek confluence is slightly off-color as the new flows settle in. The upper river is currently seeing strong blue winged olive hatches n the afternoons, and the week's cloudy forecast could make for some stellar dry fly fishing. The mayflies are in the #16-18 range. While we generally encourage folks to fish further downstream this time of year, the upper river definitely provides some excellent SOLITUDE. And, with the longer days and warmer nights, we are seeing an uptick in bug/fish activity, including plenty of midges and some strong blue wing olive hatches as far upstream as Granite. Focus on the deeper, slower water in the mornings with a stonefly and a midge, and hope for hatches in the afternoon! Fish will respond to stonefly nymphs, caddis larva, and midges, with blue winged olive patterns turning on in the afternoons. Expect subtle takes! May 9th- Middle River: The slight bump in the release from Twin Lakes paired with a couple active ditches above Salida are discoloring the river a little, but conditions are still very fishable today. Flows seem to have levelled out and clarity will return to the river the remainder of the week. Fish are moving towards the edges and pockets to escape the increasing flow, and toda'ys trips reporting in the afternoon found plenty of fish nymphing in the morning, and looking up in the afternoon. Through we've primarily encountered great midge and blue winged olive hatches north of Salida, caddis are now beginning to hatch above town. One report had a great emergence at Hecla Junction over the weekend. Caddis larva and pupa in the morning and mid-day are productive, and a caddis/baetis combo in the afternoon should yield good results. The potential afternoon cloud cover this week could make for some great blue wing hatches! May 9th - Below Salida: The river looks excellent around Salida this morning. Fish are foraging heavily throughout the day, eating stonefly nymphs, caddis and baetis patterns subsurface in the morning, with afternoon activity shifting more to surface caddis and suspended pupa on sunny days, and blue winged olives on cloudy days. Flows have leveled out, and the clarity of the river is far better than the past couple of days. Fish are definitely moving towards the edges and shallows where they are protected from the current. Don't ignore the edges! Today's potential cloud cover this week could make for some blue winged olive hatches this afternoon, whereas sunny days we will likely see caddis. Be prepared for anything in the lower canyon. Currently, we are seeing strong morning midge activity, blue wing olive mayfly nymphal drifts throughout the afternoon, and several varieties/sizes of adult caddis. We also are seeing significant cranefly activity, and at times this week fish have preferred them to the caddis. A warm winter and low flows since January have generated optimal feeding conditions for our brown trout population and most of the fish are in excellent condition. This hatch will continue to be experienced further upstream as the water warms.

Crawford State Park

Mancos

As of 5/4/2018, The lake is open water and has been stocked with thousands of rainbow trout already this spring. Additional stockings will occur through the summer. Mancos is a great place for consistent action from trout and yellow perch. Most of the trout action is from 10-12 inch fish, but there's very good opportunity at an 18-20" trout and a few 12"-plus perch. Great opportunity for kids to catch fish. Most anglers are finding success with bait (PowerBait, eggs, and crawlers) fishing just off bottom or under a slip bobber. For a chance at the yellow perch and trout, a small jig fished under a bobber on a long leader and tipped with a piece of worm is a good bet. Casting or trolling typical in-line spinners (Panther Martins, Mepps) from boats is another approach at the trout. Hand-launchable boats (non-motorized kayaks, canoes, belly boats, etc) are a great way to fish the lake in this off-season. This is the first year in more than 15 years that the lake has not gotten decent ice to fish.A park pass is required on vehicles in the park. Daily park passes are available at the self-serve pay station at the park entrance.
Mancos State Park

Navajo State Park
